The opening theme song "Rumors" performed by Auston Lam, and composed by Alan Cheung was released on July 26 in 2019 by The Voice Entertainment Group limited.

The local urban legend of the Bride's Pool, located near Tai Mei Tuk in Plover Cove Country Park was used as the setting for the introductory episodes of the series.

The bride, along with the sedan fell into the connecting river and she was trapped by the waterfall and washed into the pool below where she drowned, unable to escape due to her heavy wedding dress.

[6] In the Hong Kong legend, the bride's spirit would wander the area and favoured the nearby winding road, giving it the nickname "deadly curve".

In the 1970s and 1980s, the reports of a gigantic mother ship mysteriously hovering over Wah Fu Estate is Hong Kong's most enduring urban UFO myth.

Tai Mo Shan is the highest peak in Hong Kong and located at approximately the geographical centre of the New Territories.

The building was erected in 1974[citation needed] and was originally based on the centuries-old Yu Kiu Ancestral Hall [zh] in Ping Shan.

[8] The village where the school is located has a history of tragedy, with local residents killed and buried in the area after resisting British efforts to evict them from their land.

It has been said that a large number of villagers were massacred in 1941 during the Japanese occupation of Hong Kong, with their remains buried in graves built into the hillside next to the school.

Hong Kong people believe they are descended from this ancient fish-like creature, which transformed into a human body some time in the past 2,000 years.

Chi-Pok also runs into his colleague Wong Yuk, who was taking wedding photos by the Bride's pool and met face-to-face with strange supernatural activities.

Despising that someone exploited the tales to commit a crime, Doh-lai together with Tak-lei, Chi-pok and Wong Yuk return to the Bride's pool to investigate the matter.

Doh-lai packs up Tung-ming's relics and finds the Hong Kong Urban Folklore index and encourages Chi-Pok to complete the paper as a farewell to his father.

[7] When filming a meteor show on Tai Mo Shan, Chi-pok notices that there is something wrong with the photos, thus reviving the heated conversation about UFOs.

The successor of Ko Yuen Group, Hui Hok-Ting, secretly returns from the United Kingdom to Hong Kong.
